I think it does, as the OP was asking what Haskell is great at. Clojure actively positions itself as a language great for data transformations, as does the community, where Haskell doesn’t particularly tailor towards this. In fact this is the first time I ever heard someone say that Haskell is a great choice for that.

I hear many more Haskellers argue it’s a great language for writing parsers, and with that I very much agree.

But positioning as such doesn't necessarily make it true. Just because Haskell isn't advertised as the "data transformation" language doesn't mean it does better or worse than any other language at it.

In my personal experience of using Clojure, Haskell and Python for data transformation and parsers, Haskell does the best job for both. So this is the second time you hear it ;) Anyway, we are just throwing anecdata at each other. Personal stories are still useful for programming experiences since "which is better" isn't that easy to measure. I would be happy to hear more about your experiences with Clojure.
